HARVESTlNG-IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 414,164, dated October 29, 1889.

Application filed February l2, 1889. Serial No. 299,596. (No model.)

To coll whom it 12mg/ concern:

Be it known that I, MARION L. NICHOLS, of New York, county of New York, State of New York, have invented new and useful Improve ments in Harvesti11g-Machines, of which the following is a full and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to that class of machines in which the frame is supported on three or more wheels, the master-wheel being located in rear of the machine, the front supporting-wheel in advance of the cutters, and an end or grain wheel, the grain being carried to the binding devices between the front and rear supporting-wheels.

The invention consists in a novel manner of controlling the movements of the front supporting-wheel and the relation of themain frame relative thereto and to the ground.

It further consists in certain novel features in the construction and arrangement of parts, all as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a plan or top view of a harvesting-machine, showing the portion of the frame adjacent to the grain-wheel broken away. Fig. 2 is a perspective view of the front supporting-wheel, showing the means for connecting the same with the main frame, and also the tongue and the mechanism or gearing by which an accelerated speed is imparted to the wheel by the tongue, and showing the lifting-post. Fig. 3 is a similar view showing the mechanism or gearing to provide for the necessary vibration of the tongue consequent to the movement of the team without acting on the wheel to turn the saine, and Figs. et and 5 are detached views of the gearing that is connected to the tongue and the intermediate gearing with which the same engages. Fig. 6 is a plan or top view of the parts shown in Fig. 2. Fig. 7 is a perspective view of a portion of one of the rear frame-bars of the machine, showing the angle-frame connected thereto and one means for connecting the masteiewheel frame with the angle-frame. Fig. 8 is an end view of the frame, showing the grain-wheel, its arm, and the means for connecting the said arm to the main frame. Fig. 9 is a plan or top view of the machine, showing the wheels and the position the front supporting-wheel is caused to assumein turning the machine, and the line or track. in which said wheel and the grain-wheel are caused to travel in turning the machine. Fig. 10 is a perspective view, similar to Figs. 2 and 3, of a modification of the devices for operating and controlling the front supportingwheel i-n the movements of the tongue. Fig. ll is a plan or top view of the same, and Fig. 12 is a longitudinal section through the device.

. The main frame is made in an oblong rectn angular form, having the rear frame-bars A A, front sill or angle-bar A', cross-bars A2, longitudinal bar A3, and end frame-bar A5. The rear frame-bars A and cross-bars A2 are preferably made of metal tubing or gas-pipe, while the front sill is made in the usual angle form, to which the fingers are attached.

The rear frame-bars A A have connected thereto adjacent to the cross-bars A2 an angular frame B, having bearings b l) b formed therein for the different shafts from which motion is communicated to the various mechanisms for cutting, delivering, and binding the grain. The master-wheel franiel) is connected to this frame B through end bolts d, engaging the side bars thereof, and the lugs or ears d', formed with said frame B, and by a central bolt d2, engaging a liange d3, depending from the lower face of said frame B, and said masteuwheel frame consists, preferably, of the side bars D D, connected with the central cross-bar to form an open-ended frame, and in the ends of the side bars D D are formed or connected the bearings for the aXle E of the master-Wheel E. Brace-rods F are connected to the side bars D D and to the frame B to strengthen and forni a more rigid connection between the frames B and D.

The front sill or anglebar A has mounted thereon near the inner end of the cutting apparatus a lifting-post G, hereinafter referred to. A. frame or horn II, bent at its inner portion to conform to the shape of the lifting-post, is provided with arms II H', through which it is secured to a forward ex-a tension of the bar A by means of bolts h. From. the frame or horn H, from a point on each side of the lifting-post, the arms H of the frame H extend outward and upward in curved form, and have formed on their upper ends journals h', on Which the lifting-levers, hereinafter referred to, are mounted.

To the ends of the levers I I is connected a saddle K, to which is connected the frontsupporting-wheel holder K', and which Wheelholder has extending from the upper face thereof a journal or pin K2, Which extends through the saddle K and has mounted on its upper end a toothed Wheel or gear K3.

To the rear end of the tongue is rigidly connected a segmental toothed rack 1&4, and said tongue is mounted on a vertical pivot K5 near the ',front end of the saddle K, the toothed face of the segmental rack being formed on the arc of a circle of which the pivot-pin K5 is the center, and the toothed rack is also provided With an elongated curved slotL adjacent to the teeth and formed on a similar arc of a'circle, and which slot is engaged by a pinor stud L', projecting centrally from the saddle K, and which pin or stud-serves to limit the swinging movement of' the tongue. A second toothed wheel' orr gear K5 is mounted on a stud or pin on the saddle and meshes with the rack and with the toothed wheel or gear K3, and from which it will be seen that as the tongue is moved to either side of a right line sufficient to turn the machine the rack Will communicate motion to the' gear K, and through it to the gear K3, and consequently cause the supporting-Wheel to be turned in its bearings and to beiturn'ed at right angles tothe'master-Wheel,

the master-Wheel as a center, and the said front Wheel to track in the arc of a circle of' which the master-Wheel is the center, the slot and pin before referred to serving to limit the movement of the tongue, and consequently only permitting'said gearing to turn said Wheel to the proper angle.

In Figs. 3, 4L, and 5 the segmentalk toothed rack is shownfas cut away or mutilated, and is provided at this point with a lugv or delaysurface` engaging a corresponding lug or de- A lay-surface on the gear K5, the engaging-faces being curved in the arc of acircle corresponding to the curve of. the rack, and by means of which lugs the tongue is permitted to 'have sufficient side play "consequent to the movement imparted thereto by the team, or to permit of the necessary vibration of the tongue Without act-ing on the Wheel'to turn the same out of line.

In the modification shown in Figs. lO, 11, and l2 the intermediate toothed gear K, for causing the gear on the pivot of the Wheel to i move in a proper direction, is dispensed with,

and in this case an internally-toothed segment-,K7 is emplcyechwhich fits over or around andengages the teeth of the toothed gear K8 on the opposite side of its pivot from that shown in the other views, and by which Qonstruction it will be seen that the propermovement is imparted to the gear KB on the wheelpivot to permit the gear K, as above stated,

to be dispensed With, and also to bring the device into more compact form. The internally-toothed segment may be provided with a suitable cap or cover K8, secured toor cast therewith to cover the gear-teeth formed thereon, and also the toothed Wheel or gear K3. The cap or cover Ks is provided with a similar slot I, to engage stop-pin L', as before described. By this manner of connecting the tongue through the gear With the front supporting-Wheel holder, as above described, it

4 will be seen that an accelerated speed is imparted to the Wheel by the tongue consequent to the radius ofthe rack or segment being greater than that of the gear, and that as a consequence it Will be only necessary to turn the team slightly to properly turn the machine.l

The rear ends of the levers I I are'connected to a chain I', which chain passes up overV a roller I2, mounted in suitable bearings in the lifting-post, and being connected to a shaft or Windlass l, also mounted in bearings in the lifting-post, and which shaft or Windlass is revolved 'to Wind the chain thereon by any suitable mechanism, preferably a Worm and gear It If?, as shown. i mounted Von the end of a bell-crank lever or 1 arms M', connected to the main frame about 2 centrally of the Width of the machine from l front to rear, and having the arm on which the axle for said Wheel is formed or connect-ed to extend back, so that said axle shall be in line or nearlyin line with the rear framef bar of the machine, and the frame is provided and the machine to be swung` or turned on 1 The grain-Wheel M is with a guideway or track having a slot formed therein'in the arc' of a circle of which the pivot of the lever is the center in the usual or any preferred Way, and from which it will be seen that, While the suppointing-point for the frame on the Wheel is near the center of the Width from front to rearofY the machine, sai-d Wheel is brought into a proper position vrelative to the masterlwhcelto track on a circle aroundthe masterwvheel in turning the machine, and consequently the sliding or end movement of said grain-'wheel in turning the machine is prevented.

The master-Wheel frame has been described as having a fixed relation to the main frame; but it Will be readily seen that the front Wheel and mechanism for actuating the same Vmay IOO IIO

be used in connection with a master-Wheel IZO eling front supporting-Wheel, a tongue, gearing actuated by the tongue for controlling the movements of said front supporting-Wheel provided with engaging delay-surfaces, substantially as described, whereby the tongue shall have sufficient side play consequent to the movement of the team Without acting on the Wheel, as set forth.

In testimony whereof I have hereunto set my hand this 9th day of February, A.D. 1889.

MARION L. NICHOLS.
